Photoelectric photometry of M-type stars UBVRI photoelectric photometry was obtained for 110 M-type starscontained in the Caltech Two-Micron Survey and the revised AFGL Catalog.Of the 110 stars, 58 have a color index (B-R) greater than or equal to 4mag. A graph is given of (V-R) versus (V-I) for the present stars.
| A low-detection limit search for OH emission from infrared stars We have used the 300 m telescope of the Arecibo Observatory to examine154 cool luminous stars for 18 cm OH emission. Six of the stars (RU Ari,R Com, T Com, RX Oph, UU Peg, and RT Vir) were found to show OHemission. For the stars without OH emission, we have establisheddetection limits several times smaller than those of previous surveys.
| Constraints on the molecular properties of interstellar X-ogen derived from radio observations Twenty-eight X-ogen emission sources at 89.189 GHz have been detectedand observed. Twenty of these are new X-ogen sources which also containother interstellar molecules. No infrared stars are found to be X-ogensources. A new rest frequency (89,188.65 MHz) is derived for X-ogen. Itis shown that X-ogen is not SiC, C2H, or any molecule withspin-doubling, hyperfine structure, or both.
